Abstract
A process for producing monomers is disclosed. The process comprises hydrocracking a pyrolysis oil stream in a hydrocracking reactor over a hydrocracking catalyst in the presence of a hydrocracking hydrogen stream at hydrocracking conditions to open rings present in said pyrolysis oil stream to produce a hydrocracked effluent stream. The hydrocracked effluent stream is fractionating in a fractionation column to provide a naphtha stream. The naphtha stream is contacted with a NEP catalyst and hydrogen to produce a light paraffinic stream or with a reforming catalyst to produce an aromatics stream.
